※ 引述《sjory (我是肥企鵝...)》之銘言:
: 從x4-640換成ryzen2600
: 相關設備也一併更換
: 還特地將異塵餘生4從硬碟裝到新買的mx500裡
: cpu的使用率從x4-640的4個100%變成12個執行緒的15~40%
: 但進入遊戲或場景讀取的速度並沒有感覺變快
: 請問為什麼會這樣呢?
以一個只會看簡單數據和實測影片的消費者來看
首先你可以很簡單的找到1T硬碟的大概讀取速率,以我手上的Toshiba DT01ACA100而言
人家實測平均約140MB/s,我自己實測也差不多,傳大檔速度還會更快

再來看MX500理論數據,標榜連續讀取560MB/s
可以無腦說"理論上"讀取時間應該是HDD的四分之一倍,而實際不如理論是可預期的
那實際上呢?以原價屋Optane開箱文那兩隻實測影片來講
開機完成速度 LOL 讀取速度
HDD: 1:48以上(沒測完) 0:40
SSD: 0:18 0:21
請注意在此SSD用的還是600P,理論讀取高了MX500三倍,高HDD實際讀取近10倍的情況下
但開機時間僅為HDD的六分之一不到,LOL讀取時間僅為二分之一
二分之一是甚麼概念?
光是LOL讀取就要40秒,大作就算90秒好了,看著讀取畫面90秒→45秒,就只是很久→久
更別說實際值MX500會比600P還差
這點我把GTA5從HDD移到MX300之後很有感。能感覺讀取時間縮短,但還是等到不耐煩
只能說SATA SSD頂多滿足開機,開小程式加速有感,遊戲讀取有感還是得靠M.2 PCIE,PCIE
--
以上~發這篇意欲拋磚引玉,我只是一個會看簡單數據和實測影片的消費者而已
4k讀取,Cache大小那些都一知半解,期待有大神能講出達不到理論速度的細部原因啦~
